Microsoft Flight Simulator, FS9P

I I´m testing/trying NOD32, seems to be a good antivirus, in the same leauge as KAV. But my problem is that FS9 keeps crashing, tried the suggestions.

tried this
"In order to exclude fs9 from the monitoring list I added fs9.exe to the AMON exclusion list, not the IMON exclusion list. Now that fs9.exe is included in the IMON list everything now seems to be working well."

But not any luck with it, anybody have som other suggestion?
Then you would make my day...
